Abstract

L'invention concerne un support d'enregistrement d'informations optiques (200) qui comprend une structure dans laquelle une couche d'émission de lumière (10), une première couche d'enregistrement d'informations (20), une couche intermédiaire (30), une seconde couche d'enregistrement d'informations (40) et un substrat (50) sont stratifiés dans cet ordre depuis un côté d'entrée de faisceau d'enregistrement. La première couche d'enregistrement d'informations (20) lit des informations et la seconde couche d'enregistrement d'informations (40) comprend une région où des informations peuvent être réécrites. La première couche d'enregistrement d'informations (20) a une caractéristique d'émission de lumière et la réflectance de la première couche d'enregistrement d'informations (20) à une longueur d'onde de faisceau d'enregistrement est plus élevée que 0,4 % mais n'est pas supérieure à 2,2 %. Ainsi, par le support d'enregistrement d'informations optique hybride, des informations sur le support peuvent être reproduites même par un appareil d'entraînement applicable à d'anciens supports d'enregistrement d'informations optiques standards ayant un petit nombre de couches d'enregistrement d'informations et la capacité d'enregistrement peut être améliorée par ajout d'une couche destinée seulement à l'enregistrement (couche ROM) ou d'une couche d'enregistrement supplémentaire (couche R) aux anciens supports d'enregistrement d'informations optiques standards.
